This study shows that Parkinson's disease preserves the speed and strength of a reflexive visuomotor response but impairs its contextual modulation, suggesting distinct motor pathways are affected.

This study shows that Rhesus Macaques exhibit express visuomotor responses in upper limb muscles with latencies of ~65 ms, similar to humans but faster, suggesting shared but distinct visuomotor transformation mechanisms.

The paper shows express arm responses occur bilaterally in upper-limb muscles during reaching tasks, supporting the involvement of the reticulo-spinal tract.

The paper investigates how visual features like high contrast and fast movement influence rapid visuomotor responses during reaching, showing that these features elicit strong muscle responses and faster reaction times.

This paper introduces a new behavioral paradigm that consistently evokes robust fast visuomotor responses in human upper limb muscles during visually guided reaches.

The paper investigates how visual stimuli with different spatial frequencies affect rapid visuomotor responses, finding that low spatial frequencies evoke the fastest and most prevalent responses.
